I liked your style, straight to the point, but I think I would have to see more of the story to be able to develop a real thought about it. When it comes to the theme, you respected it all right, and the Attack on Titan (but not really) approach to it is interesting, especially since your story implies that there's more to it. As for presentation, you did the effort to modify images and to have some additions to the basic sprites that were offered to us, and I appreciate these details!
